Looking for a simple, warranty-friendly upgrade for your car? The VWR High-Flow Panel Air Filters, available for most Volkswagen Group TSI and TDI cars replace the restrictive factory paper filters with an improved, high flow and reusable lifetime triple-layer Trifoam® filter. Put simply, it’s the best Panel Air Filter you can buy.
The filter is one of the most cost-effective enhancements you can make to set your engine free by allowing it to breathe better and operate more efficiently – improve the engine’s airflow, and power and fuel economy gains will follow. By removing the inevitable restrictions that the standard paper panel filter gives, the VWR Panel Filter allows a small but worthwhile increase in airflow through to the turbo. A great match for a Stage 1 OEM+ remap or a standard car.
The result? More mid-range power and improved economy, without wrecking your warranty.
Trifoam® filter construction, triple-layer laminate of open-cell polyurethane foam, which gives an exceptionally high level of filtration – the very same technology as Formula One engines use.
Fitting couldn’t be more simple: remove the standard paper filter, and drop in the VWR High-Flow filter. And easily returned to standard should you ever wish.
Hand-built in the UK, the triple foam layers are held in place by a stainless steel open mesh, surrounded by a poured polyurethane moulded seal to provide an airtight seal against the standard airbox.
Efficient filtration means mid-range torque gains. A small economy improvement is often reported back to us by customers.
This is a 'lifetime' filter, so never needs replacement in normal service. Cleaning is only required every 20,000 miles (30,000km) in normal usage.
/// With the extra airflow that the fitment of the VWR Panel Filter gives, our tests have shown that it can deliver an additional 15NM of torque on a standard 2.0 TSI engine, thus making a small but worthwhile difference to the feeling of mid-range power of the car.
/// With the improved efficiency, many customers have noticed an improvement in fuel economy in normal driving.
/// This filter complements our OEM+ Stage 1 Power Upgrades really well, together with our VWR Exhaust Rear Section.
/// The VWR filter is unique in using a TriFoam™ triple-layer laminate of open-cell polyurethane foam, which gives an exceptionally high level of filtration to protect the engine from contaminants in the air down to well below 5 microns.
/// The TriFoam™ we specify is the best in the market - the same specification as used by certain well-known F1 teams - and the exact same material that our renowned Cold-Air Intakes use.
/// There are of course cheaper, single-layer foam panel filters on the market. We’ve tried many of these over the years; but in our experience they do not combine satisfactory levels of both flow and filtration – meaning a compromise for your engine (sometimes quite significant) for the sake of a small price difference.
/// All our filters are hand-built in the UK from the highest quality materials available.
/// We recommend that the Filter element is cleaned every 20,000 miles/30,000 km. This is a simple procedure, and will ensure that your Filter continues to deliver the airflow improvements over a standard car.
/// Our Trifoam™ material is the most advanced foam construction available. If you do not clean your Filter at the above intervals, Trifoam™ means that no loss of filtration will occur, and your engine will still be fully protected. However, the performance advantages resutling from additional airflow of a clean Filter will be lost.
/// If your car is regularly used in a dusty environment, we advise that you clean and re-oil your Filter more regularly.
/// For cleaning and re-oiling instructions, please read Stage 1 and Stage 2 on the following pages.
/// Use Racingline foam air filter cleaner. (Use ITG CL-1 cleaner if Racingline cleaner is unavailable).
/// Racingline cleaning fluid is intended to be used in a two-part cleaning process where the cleaner breaks
down the sticky dust retention oil on the filter which is then washed off using warm water.
/// Spray the cleaner liberally onto the filter and thoroughly massage in. You need to ensure the cleaner has worked its way through all the layers in the foam and it may be necessary to apply extra cleaner until you are satisfied the cleaning fluid has fully penetrated the foam. To help the cleaner to break down the oil, it is advisable to leave the filter for 2-3 minutes and then further massage the cleaner into the foam.
/// The next step is to wash the filter out in warm water. Thoroughly wash the filter until you are totally sure that
all the cleaning fluid has been removed and the water running through the filter looks clear. It is also advisable to run water through from the clean side outwards to further help the removal of any dust still held within the
filter. This stage of the process should take no more than 4–5 minutes, leaving the filter submerged in water for a prolonged period of time may cause the glues in the filter to soften and eventually break down.
/// Next follow the same process again using washing up liquid, this will help to break down any remaining cleaner still left in the filter. Apply a small amount of washing up liquid onto the filter and massage into the foam working it all the way through. Rinse the filter in cold water until none of the soap suds remain and the water runs
clear, shake the filter to remove excess water.
/// Now the filter is clean you will need to leave it in a warm, dry place until is fully dried out for a minimum
period of 24 hours. Do not use a high pressure air line or heat gun to speed the process up.
/// Never use an unoiled or dry foam filter in your vehicle as this will significantly reduce the efficiency and may allow small dust particles to pass through without being trapped by the dust retention oil.
/// Once you have completed Stage 1, cleaning your filter, and ensured it is completely dry, you are ready to perform the important stage of re-oiling it. You will need to purchase a suitable aerosol Air Filter Oil.
It is very important that this is a specific Air Filter Oil, and no sort of other product. We recommend RacingLine, Castrol, ITG or Shell branded aerosol Air Filter Oil. Read instructions and safety warnings on the product before use. Follow the instructions provided on your cleaning product; in general, the procedure is as follows:
Use in an open environment. Holding the aerosol about 25mm or 1 “ from the filter, spray in a circular motion all over the foam surface until the coarse foam pores just start to fill up with oil. Then wearing protective gloves use your finger tips to ‘massage’ the oil into the depth of the foam whilst it still feels cold to the touch. The aerosol contains a mix of oil concentrate and thinners which assist the oil to penetrate into the foam. The thinners will evaporate o after around 5-10 minutes, so massage the oil into the foam as soon as it is applied, to assist the oil in penetrating through to the fine inner layer of foam. Your filter is now ready to re-install.
